电动卷帘门选购等级如何划分？

Element 1: Certificate of conformity - the formal electric rolling door has the inspection certificate issued by the legal inspection organization and the production certificate of safety technology prevention products issued by the safety technology Prevention Department of the provincial public security department (bureau) where the manufacturer is located.

要素2:等级——等级电动卷帘门分为A、B、C3级。C级防盗性能高,B级其次,A级低,市面上多为A级,普遍适用于一般家庭。A级要求:全钢质、平开全封闭式,普通机械手工工具与便携式电动工具相互作用下,其薄弱环够抵抗非正常开启的净时间≥15分,或应不能切割出一个穿透门体的615平方厘米的洞口。

Element 2: Level - safety level the safety of electric rolling shutter door is divided into levels a, B and C3. Class C has high anti-theft performance, followed by class B, and class A is low. Most of them are class A on the market, which is generally applicable to ordinary families. Class a requirements: all steel, flat open and fully enclosed. Under the interaction of ordinary mechanical hand tools and portable electric tools, the net time for the weak link to resist abnormal opening shall be ≥ 15 minutes, or a 615 square centimeter hole penetrating the door body shall not be cut.

要素3:材质——材质目前较普遍用不锈钢,美观、耐用、防锈蚀。主要看两点:①牌号现流行的不锈钢电动卷帘门材质以牌号302、304为主;②钢板厚度门框钢板厚度不小于2cm,门扇前后面钢板厚度一般在0.8cm～1cm之间,门扇内部设有骨架和加强板。

Element 3: material - at present, stainless steel is widely used, which is beautiful, durable and anti-corrosion. There are two main points: ① the popular stainless steel electric rolling shutter doors are mainly made of grades 302 and 304; ② The thickness of steel plate is not less than 2cm for the door frame. The thickness of steel plate at the front and back of the door leaf is generally between 0.8cm and 1cm. The door leaf is internally provided with framework and reinforcing plate.

要素4:功能——电动卷帘门是否支持手动功能,手动要方便,快捷。停电时将离合扭转90度,即可手推运行。电动卷帘门不能存在惯性滑行的现象,要具有双面自动卡锁功能。为了提高电动卷帘门运行平稳程度,要增强拉力,所以需要采用的是8轮前后驱动,连排齿轮转动的生产安装技术。

Element 4: function - whether the electric rolling shutter door supports manual function, which should be convenient and fast. In case of power failure, turn the clutch 90 degrees to manually push it. The electric rolling shutter door shall not have the phenomenon of inertial sliding, and shall have the function of double-sided automatic locking. In order to improve the running stability of the electric rolling shutter door and enhance the tension, the production and installation technology of 8-wheel front and rear drive and continuous gear rotation needs to be adopted.

要素5:结构——观察电动卷帘 门的结构是否精密,润滑程度好坏,好的电动卷帘门散热比较,采用全齿轮转动,无链条、无皮带,进而增强了卷帘门机芯整体寿命。

Element 5: structure - observe whether the structure of the electric rolling shutter door is precise and whether the lubrication degree is good or not. A good electric rolling shutter door has better heat dissipation. It adopts full gear rotation without chain and belt, so as to enhance the overall service life of the rolling shutter door movement.
